CLEVELAND—Arkema Inc. showcased Vul-Cup 40C-SP2, a crosslinking peroxide designed to answer the needs of the North American rubber and elastomers industry because of recent changes in the market for chlorinated polyethylene during the recent International Elastomer Conference in Cleveland.
Current conditions call for compounders to increase processing time and temperature, according to Arkema. The firm said Vul-Cup 40C-SP2 combines Arkema's unique scorch protection technology with Vul-Cup peroxides.
Vul-Cup 40C-SP2 is a new development based on technology Arkema developed 10 years ago, according to Michael Sauerwald, Arkema senior marketing specialist for functional additives.
“It was based on the Luperox molecule made in Europe,” Sauerwald said.
“Now we've more or less merged the technology with the Vul-Cup molecule made here in the U.S. The entire idea is the prevention of scorch,” he said. “It's been more important lately, as changes in the market have affected compounds with CPE.”
Vul-Cup 40C-SP2 allows higher processing temperatures for CPE compounds, cutting production times and reducing losses due to scorch, Arkema said.
